💖 xcb_randr_get_crtc_gamma_size(3) 💖

okay bestie, welcome to the XCB Requests corner of the manual, where we talk about xcb_randr_get_crtc_gamma_size — yes that name is a mouthful, no we are not shortening it, it's iconic 💅

✨ NAME ✨

xcb_randr_get_crtc_gamma_size —

bestie the description line is literally empty 😭 like the manpage authors left it blank, so I'm not gonna invent lore. The name is the whole vibe here.

🌸 SYNOPSIS 🌸

First things first, you gotta pull in the header:

#include <xcb/randr.h>

🎀 Request function

xcb_randr_get_crtc_gamma_size_cookie_t
       xcb_randr_get_crtc_gamma_size(xcb_connection_t *conn,
       xcb_randr_crtc_t crtc);

🦋 Reply datastructure

typedef struct xcb_randr_get_crtc_gamma_size_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint16_t size;
    uint8_t  pad1[22];
} xcb_randr_get_crtc_gamma_size_reply_t;

⭐ Reply function

xcb_randr_get_crtc_gamma_size_reply_t
       *xcb_randr_get_crtc_gamma_size_reply(xcb_connection_t *conn,

       xcb_generic_error_t **e);

💜 REQUEST ARGUMENTS 💜

• conn — the XCB connection to X11. your lil hotline to the server, she's the main character fr fr 👑
• crtc — TODO: NOT YET DOCUMENTED. yeah babe, they just never wrote it down 🙈 the manpage says what it says and I'm not out here guessing, no cap.

---

🌈 REPLY FIELDS 🌈

• response_type — the type of this reply, which in this case is XCB_RANDR_GET_CRTC_GAMMA_SIZE. This field is also hanging out in the xcb_generic_reply_t, so you can use it to tell your replies apart from each other. it's giving "hi it's me, your reply" 💖
• sequence — the sequence number of the last request processed by the X11 server. the receipts, basically 🧾✨
• length — the length of the reply, in words. and reminder bestie, a word is 4 bytes 📏
• size — TODO: NOT YET DOCUMENTED. again!! the mystery field 😭 she's mysterious, she's undocumented, we respect her privacy.

💀 DESCRIPTION 💀

it's empty. literally nothing here. the section exists and it is a void 🕳️✨ we move on.

---

🫶 RETURN VALUE 🫶

So this hands you back an xcb_randr_get_crtc_gamma_size_cookie_t 🍪 (yes a cookie, slay). Errors have to be handled when you call the reply function xcb_randr_get_crtc_gamma_size_reply.

But if you'd rather handle errors in the event loop instead, use xcb_randr_get_crtc_gamma_size_unchecked. See xcb-requests(3) for the deets 👀

🔥 ERRORS 🔥

🎀 SEE ALSO 🎀
